printf and escapes

Learn formatted output with printf and escape sequences.

printf and format specifiers

The printf function writes formatted text to the screen. Format specifiers tell how to print variables:

Escape sequences represent special characters: \n new line, \t tab, \\ backslash.

You can print multiple variables in a single printf call. The order of specifiers must match the order of arguments:

int age = 25;
double height = 1.75;
printf("Age: %d, Height: %f", age, height);

Output: Age: 25, Height: 1.750000

The number of specifiers must match the number of arguments; otherwise undefined behavior occurs.

Print int n = 5; as Result: 5 using printf. Use the %d specifier.

Show example solution

#include <stdio.h>

int main(void) {
    int n = 5;
    printf("Result: %d", n);
    return 0;
}

Integer specifier

printf("Result: ____", 5);
